ABSTRACT:
An optical media disc protector comprising a transparent plastic disc formed in a substantially circular configuration with a center-hole, and a temporary adhesive applied to one side of said plastic disc for removable bonding with a media disc. The laser of a conventional player can read the contents of the optical disk through the disc protector.In one embodiment, water-soluble adhesive is applied to one side of the optical media disc protector, such as in an inner ring around the center-hole, and a peripheral outer ring.In another embodiment, the transparent plastic disc is formed in a substantially circular configuration with a center-hole and a plurality of axial tabs protruding from about its periphery. Temporary pressure-sensitive adhesive is applied to one side of each of the tabs.In both cases a removable backing may be supplied to protect the adhesive until application. Both embodiments are used by removing the backing and applying the disc protector to cover the read side of the optical media, using the temporary adhesive to bond. If a disc protector is damaged, it can easily be removed and replaced.
